m M w vided with chambers 22 and 23.

I At 20,is indicated a conducting pipe providing a conduit for oil from the distributing pipe 7. to the manifold. A casting or valve housing 21 is provided and is threaded in the wall of the manifold. It is pro- Between andleommunicatin with these chambers is a comparatively arge aperture 2-1; and

opening. within the manifold and communieating with chamber 23 is an aperture 25 6 having a comparatively large bore. A

--spiral spring v26 is mounted within cham- -'ber 23' and the spring is provided with a ball valve 27. /Spring.26, is constructed of light material and while itefi'ectively prevents the passage of oil or air outwardly of a the manifold, itofi'ers only a slight resistance to the passageof oil from pipe 7 to the manifold.

Q jifPipe' 8 is provided with check valve 28 b which prevents a return of the oil after it centers the pump from pipe 6, and the distributing pipe is provided Withstop cock 29. When starting the engine, all that is.

necessary, after the pump handle has been 'fted, is to -movethe handle of the pump o the ump, since check valve 28 'at this will be closed, oil will enter and will compressed in pipe 7, and this pipe op- 0 crates-as an equahzing chamber, and there-- fore oil in uniform quantities will be inject- .ed within each cylinder, and since it will ass out of the nozzles 'with considerable orce, it will be atomized, ready to be ignited 451byoperation of a spark-plug (not shown), .'.and by these means the cylinders are pruned for the purpose described. At the time the oil is atomized in the cylinders by the down- ;ward movement of the pump handle, a supsoi ply of'oil will flow through passageway 25 -wi-t-hinthemanifol'd. It will not be atomized h wever, since spring 26 is of such construc on thatitofi'ers only a slight resistanceto the oil,,a nozzle not being employed. The parts areso adjusted and ar e of such proportion that a fsuflicient quantity of oil ill pass within "the? man1 fold to maintain the cylinders for ten or twelve revolut1ons of theengine shaft, at which time, by-operation of suction, the manifold Wlll be supplied with fuel from the carbureter. Thereafter, while the engine is operating, all of the oil which remainsin the distributing pipe 7 will pass within the cylinders and manifold from suction, stop cock 29 being ownwardl ,cock 29 being open. By actionclose d. Since springs 18 are stronger and provide a greater resistance, the greater part of the'oil by operation of suction will pass'within the manifold. The operation justdescribed may be repeated, as often as required, and the use 'of the crank for starting the rotation of' the engine shaft may be avoided.

I It is necessary occasionally to clean the interior walls of the cylinders and mani fold, since they become foul, and this is best accomplished by use of kerosene.

v At 30 is indicated a supply receptacle'for kerosene oil, said receptacle having a c011- ducting pipe 31 provided with a 3-way valve 32. By'manua-lly rotating the cylinder of the 3way valve 32, a flow from pipe 8 will be prevented and a supply of kerosene may be drawn within the barrel of pump 10, and the cylinders and manifold may be charged with the kerosene, by use of-the pump, inthe manner already described. The barrel of'the pump is preferably constructed of glass, so that its contents and operation may be visible.' While 1' have shown the pump and reservoir for the kerosene as mounted upon the dash of the automobile, they of course, may be located upon some other part, if desired.

Among some of the advantages of the herein described priming attachment, it may ,be stated that the parts are few and convenient in manufacture, and it may be mounted ope'ratively, by any mechanic of ordinary skill, witlTut changing any of the original parts of an engine and by its use the objectionable and often'dangerous practice of cranking the engine may be avoided. Kerosene has for a long time been used as a preferred substancejto be burned within the cylinders and manifold as a cleaning agent, but these parts have not been convenient of access. As already explained, the kerosene, while entirely separated from the gasolene, may be-readlly conducted to these parts, and no additional carrier for kerosene is needed, than the devicesdescribed.

Having fully explained my invention, what I claim and desire to secure by Letters Patent is,'

1. In combination with the cylinders and manifold of a gasolene engine, a distributing pipe for liquid fuel disposed horizontally above thecylinders and manifold, said pipe having a plurality of tubular members, each being in communication with a cylinder, and provided with a conduit communieating with the manifold;

vided' for the conduit and for each of said tubular members; and means tocompress the liquid fuel within the distributing pipe for actuating said valves.

2. A priming device for gasolene engines, comprising, in combination with the cyla valve pro-&

' 1 pipe to open said valves.
